Area and Volume

6. The common endpoint of two or more rays or line segments
11. A 3-dimensional figure that has polygons as faces.
13. A polyhedron with two parallel and congruent faces, called bases, and all other faces that are parallelograms.
15. The number of square units it takes to completely fill a space or surface.
16. A triangle which has all three of its sides equal in length.
17. A number of coplanar line segments, each connected end to end to form a closed shape. A regular polygon has all sides equal and all interior angles equal.
18. A 4-sided polygon where all interior angles are 90°.
19. A quadrilateral with both pairs of opposite sides parallel.
20. One of the polygons that makes up a polyhedron.
22. A prism whose bases are triangles. A solid (3-dimensional object what has five faces: three rectangles and two bases.)
24. The amount of space occupied by an object.

1. A closed figure consisting of three line segments linked end-to-end. A 3-sided polygon
2. Volume of the solids is measured in Cubic Units.
3. Four coplanar line segments linked end to end to create a closed figure. A 4-sided polygon.
4. A two-dimensional figure that, when folded, forms the surfaces of a three- dimensional object.
5. A triangle where one of its interior angles is a right angle (90 degrees).
7. A triangle where all three sides are different in length.
8. A triangle which has two of its sides equal in length.
9. The total area of the 2-dimensional surfaces that make up a 3-dimensional object.
10. In a prism, a face that is not a base of the figure.
12. The intersection of a pair of faces in a three-dimensional figure.
14. A quadrilateral that has four right angles and four equal sides.
21. A quadrilateral which has one pair of parallel sides.
23. A quadrilateral with all four sides equal in length.
